DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unicycle.

[0002]

2. Description of the Related Art The conventional technique is to attach a roller to shoes,
It was a so-called skate in which rollers were mounted on a sliding board, or a unicycle in which wheels and pedals were integrally rotated. The rollers of this skate had small wheels and could not be used on bumpy roads, and unicycles could not run at high speed.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a unicycle capable of running at high speed even on uneven roads and easily braking.

[0004]

The present invention is configured as follows. 1. By a wheel with a tire mounted on the periphery, its axle, a pair of foot pedals connected to this axle and downwardly stable on both sides thereof, and a shin pad plate connected to the axle and upwardly stable on both sides by gravity A unicycle characterized by comprising. 2. A wheel having a tire mounted on a peripheral portion thereof, an axle thereof, a pair of foot pedals connected to the axle and being stabilized by gravity downward on both sides thereof, a shin plate connected to the axle and extending upward on both sides thereof, A unicycle comprising a hand-held part extending upward from a connection part of a shin pad. 3. 3. The unicycle according to claim 1, wherein the wheel and the axle rotate integrally, and the axle and the foot pedal are connected via a ratchet mechanism rotatable in one direction. 4. 4. The unicycle according to claim 1, wherein a brake member which operates in contact with the ground or in contact with the wheel is connected to the foot pedal or the shin pad. 5. The unicycle according to any one of claims 1 to 3, further comprising a brake member that is mounted on the shin-contacting plate portion and that operates by contacting the wheel by pushing with a foot.

[0005]

[Constitution 1] In the present invention, as shown in FIG.
, A wheel axle 2 thereof, a pair of foot pedals 3 connected to the axle and downwardly on both sides thereof, and stabilized by gravity, and a shin pad 4 connected to the axle and upwardly stabilized on both sides by gravity.
This constitutes a unicycle. The tire is optimally an elastic pneumatic rubber tire. A bearing may be interposed between the wheel and the axle or between the axle and the foot pedal to reduce friction. The foot pedal and the shin pad may be integrated, but are preferably divided. When the two are divided, a counterweight for stabilizing the shin plate upward by gravity may be provided on the shin plate. The shin plate 4 is preferably provided with a brake 5 which presses the wheel with the foot.

[0006]

[Function 1] The impact on the human body can be reduced by mounting the tire 1 on the periphery of the wheel, preferably by using an elastic pneumatic rubber tire. Since the pedal 3 connected to the wheel axle 2 is stabilized downward by gravity on both sides, the foot pedal can easily be put on the foot pedal at the most stable position at any time. Also, by stabilizing the shin pad 4 connected to the axle 2 upward, which is the most necessary position, by gravity, the shin pad can be supported by the foot and the posture of the unicycle can be easily controlled by the foot. Become. Further, by interposing a bearing between the wheel and the axle or between the axle and the foot pedal, even when the wheel rotates, the pedal can be stopped and the foot can be rested.

[0007]

Embodiment 1 As shown in FIG. 1, a wheel having a tire 1 mounted on a peripheral portion thereof, an axle 2 thereof, a pair of foot pedals 3 connected to the axle and stabilized by gravity below both sides thereof, and connected to the axle. A unicycle characterized by comprising a shin paddle 4 which is stabilized by gravity above both sides thereof.

[0008]

The present invention relates to a tire according to the present invention, as shown in FIG.
Axle 2, an axle 2 thereof, a pair of foot pedals 3 connected to the axle and downwardly on both sides thereof and stabilized by gravity, a shin paddle 4 connected to the axle and extending upward on both sides, and a shin on both sides. A unicycle is constituted by the hand-held portion 6 extending upward from the connecting portion of the backing plate. In addition to the configuration described in Configuration 1,
It has a hand portion that extends upward from the connecting portion of the shin pads on both sides, and by having this hand portion, the shin pad can be positioned above the axle. There is no need to stabilize by gravity.

[0009]

[Function 2] In addition to the functions and effects described in the function 1, a hand holding portion is provided by connecting the shin pads on both sides. By having the hand holding portion, the posture can be easily stabilized. Also, since the shin pad can be positioned above the axle, it is not necessary to stabilize the shin pad by gravity.

[0010]

Second Embodiment As shown in FIG. 2, a wheel having a tire mounted on a peripheral portion thereof, an axle thereof, a pair of foot pedals connected to the axle and downwardly stable on both sides thereof, and both sides thereof connected to the axle. A unicycle comprising an upwardly extending shin pad and a hand-held part which connects the two shin pads and extends upward.

[0011]

Configuration 3 The unicycle according to Configuration 1 or 2, wherein the wheel and the axle rotate integrally, and the axle and the foot pedal are connected via a ratchet mechanism rotatable in one direction.

[0012]

[Action 3] In addition to the actions described in Action 1 or Action 2,
The wheel and the axle rotate integrally, and the axle and the foot pedal are connected via a ratchet mechanism that is rotatable in one direction, so that the pedal can be rotated to propel the unicycle. The ratchet mechanism can be mounted on either or both sides.

[0013]

Embodiment 3 In addition to the technology of Embodiment 1 or 2, the wheel and the axle rotate integrally, and the axle and the foot pedal are connected via a ratchet mechanism that is rotatable in one direction.

[0014]

[Structure 4] As shown in FIG. 1 or FIG.
The unicycle according to any one of claims 1 to 3, wherein a brake member 5 that operates in contact with the ground or in contact with the wheels is connected to the shin pad 4.

[0015]

Function 4 As shown in FIG. 1 or FIG. 2, the unicycle can be easily braked by connecting a brake member which operates in contact with the ground to the foot pedal portion or the shin pad portion. When a brake member that operates in contact with the ground is connected to the foot pedal, the brake member is brought into contact with the ground by tilting the foot pedal or the unicycle. Also when connecting the shin contact portion brake member, the shin contact member or the unicycle is inclined to bring the brake member into contact with the ground. In both cases, when the wheel falls backward ahead of the center of gravity of the body, the brake member automatically comes into contact with the ground, and it becomes easy to avoid the fall.

[0016]

Embodiment 4 A unicycle according to any of embodiments 1 to 3, wherein a brake member which operates in contact with the ground is connected to a foot pedal or a shin pad as shown in FIG. 1 or FIG.

[0017]

Configuration 5 A unicycle according to Configurations 1 to 3, wherein a brake member which is in contact with the wheel by being pressed by a foot is mounted on the shin plate portion.

[0018]

[Function 5] By mounting a brake member which comes into contact with the wheel by pushing on the shin pad portion with the foot, braking can be easily performed with the foot.

[0019]

Fifth Embodiment A unicycle according to any one of the first to third embodiments, wherein a brake member which operates by contacting the wheel by pressing the foot with the foot is attached to the shin pad.

[0020]

According to the present invention, it is possible to provide a unicycle that can run at high speed even on uneven roads and can be easily braked.
